What is a Projector?

A projector is an electronic device that projects an image or video onto a screen or wall. It usually consists of a light source, lens, and image capture device.

How does a projector work?

To understand how a projector works, let’s first understand how images are created. Essentially, there are two ways to create an image:

Computer projection:- Computer projection is the most common way to create images. The projector sends a file, like a movie or PowerPoint presentation, to a computer. The computer then converts the file into a graphics file that the projector can use.

Projection:- Projection is the method that projectors use to create images.

There are two types of projection:

Laser projection:- Laser image projection uses a laser to project the image instead of a projector bulb. The laser is what shines on the surface to create an image.

DLP (digital light processing) projection:- DLP is a newer technology that uses a digital light processing chip to create images. These projectors use technology like digital external projection screens and liquid crystal light processing to create images on a screen.
